EXTENSION-TABLE.

SPECIFICATION forming part of Letters Patent No. 257,274, dated May 2, 1882 Application filed November 2 5, 1881. (No model.)

T 0 all whom it may concern:

Be it known that I, NICKLAS BAUER, a citizen of the United States of America, residing at Springfield, in the county 'of Clarke and State of Ohio, have invented certain new and useful Improvements in Extension-Tables; and I do hereby declare the following to be afull, clear, and exact description of my invention, such as will enable others skilled in the art to which it appertains to make and use the same, referencebeinghad to the accompanying drawings and letters or figuresof reference marked thereon, which form a partof this specification, and in which Figure 1 is a perspective view of the two slide-bars, one above the other. Fig. 2 is a longitudinal vertical section taken on the line at w of Fig. 3. Fig. 3 is a vertical cross section taken on the line 3/ y of Fig. 2, and Fig. 4 is a vertical cross-section taken upon the line zzof Fig. 2.

My invention relates more particularly to the sliding bars of an extension-table, and has for its object a spring device to hold the slidebars together and take up any loss in wear; and it consists in the construction and arrangement of parts hereinafter more fully set forth.

In the accompanying drawings,A and B represent slide-bars used in the construction of an extension-table, provided with mortises O and D, with receding sides. These mortises, at their upper ends, are provided with flaring tenons E and F, of peculiar construction.

The tenons are preferably constructed of hickory wood or other suitable elastic material, and have their bases constructed of the required form to lit the mortise of the sliding bar in which they are secured and their tops flared so as to tit and slide easily in the opposing slide bar. Before these tenons or tongues, as they may be called, are secured in the mortise they are cut by a saw upon the line shown at G in Figs. 1,2, and 4 of the drawings, making an opening from near the center of the end across the tenons on a horizontal line, extending a short distance, then curving upward and backward a suitable distance, where it ends, thus forming a spring, H.

\Vhen placed in the mortise a screw, I, is driven through the spring H a suitable dis tance in front of the end of the saw-cut-and through the tenon into the bar, drawing the spring down as far as may be required for the requisite amount of pressure against the receding sides of the mortise in which it. travels.

Having thus described my invention, I desire to claim and secure by Letters Patent- An elastic tenon or tongue for the slide-bars of an extension-table, constructed of a single piece of hickory or other suitable material, provided with a spring, H, said spring being constructed by a saw-cut, G, extending across the tongue nearits narrowest point and backward from one end a suitable distance, and held down by a screw, I, substantially as'shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
